    Test in the other two. That would confirm that the issue is QT 10.3 and not the file.

    But it opens up other mp4s encoded in the same way. Unless the problem is the size of the mp4.

    QT7 uses Quicktime. QT 10.3 uses CoreMedia. VLC has it’s own.
    This can determine if it’s the source/encode at issue vs the ability of certain players under certain circumstances.

    I tried QT 7.6.3 and the error message read this is not a QT file even though the icon of the file is the QT symbol.

    I tried it in VLC 2.1.4. It would open the shorter one that also opens in QT but not the ones that QT would not open.

    So if all three player (VLC, QT7, QT 10.3) have issues then there would be an issue with the encode it seems.

    In HandBrake main window, you’ll see a checkbox that says “Large file size.” Enable that and try doing the encode again.

    That makes sense. Small ranges of the same timeline encoded in handbreak just fine.

    Yes. That did the trick. I checked the “Large file size.” Set the encode to slow and ended with a 5+gig file that is better than a FCP X share.

    Thanks, Craig.

    Good to hear. I wonder what the threshold for “Large File Size” is given that “large” by itself, is subjective.
    I wonder what it might be changing.
